IMP'ROVEMENT IN CASTERS.

The Schedule referred to :in these Letters Patent and making part of the same.

To all whom 'it may concern:

'Be it known that I, FREDERIC GeFoRD, ofthe city, county, and State of New York, have invented a new and useful Improvement in Roller-Casters; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawings, which form part of this v specification, and in which- Figures 1 and 2 represent vertical views of a caste constructed according to my invention, and

Figure 3, an inverted plan view Kof the same.v

Similar letters of reference indicate corresponding parts in the several gures.

This invention is more especially'desiguedfor use on such articles of household-hrniture as are constructed of soft wood, but is susceptible of a more cx- `tended application.

The invention consists in a novel construction of a caster, whereby the same may be more securely attached, and in less time than by the ordinary construction. l

Referring to the accompanying drawings- A is a roller, carried in a revolving bearing-frame,`

B, which turns upon a vertically-arranged fixed post or stud C, substantially as in other casters.v

Djs a transversely-arranged head, formed on or attached to tlie upper end of the fixed stud C.

Said transverse head D is preferably of cylindrical formation, and has formed upon its under side a reduced portion or neck, d.

In attaching this caster to such articles of householdfurniture as require casters, instead of boring a vertical hole into the foot, from the bottom thereof, as is thereto bya screw or-screws.

.secured by Letters Patent, is-

usually the .case in attachingA thev ordinary caster, a

horizontal hole is bored in the side thereof, and', near the bottom, for reception of the horizontal head D, and a slot is cut through from its lower Iside, and lengthwise thereof, 'to the under side or bottom of the foot, for reception of the neck dr. It is preferred to have the said hole'and slot small enough yto insure a tight t when the head D and neck d are` driven or forced therein.

' For preventing the slipping out of the head D when thus adjusted, a loose plate lor washer, c, may be arranged upon thexed post C, between the top of the bearing-,frame B and the bottom of the neck d, so as to tup against the bottom of the foot, and secured Or the head D may be constructedwith a jagged' peripherical surface, vofsuch nature as to permit the inward sliding of the head, but prevent its backward movement, asrepresented in fig. l. Or the entrancel ot' the opening may be plugged up with a plug, f, of wood or other material, and'glued or otherwise'secured therein. l

What I claim as my invention, and desire to have A caster, the top of which is provided with a transverse cylindrical head, D, and a neck, d, for fitting in a horizontal-hole and slot madein the side of the foot of the article to which it is designed to be attached,

substantially as herein'described.
